Elder Delbert L. Stapley explained that there is a way to become worthy to partake of the sacrament again, even in the case of transgression:
“Emphasizing as I have, the importance of worthiness in partaking of the sacrament of our Lord, maybe there are some of you, I hope not, that have a feeling you have been unworthily partaking. Remember, we have in the Church the principles of repentance, and of forgiveness. Certainly one who truly repents with all their heart and [does] the works of righteousness can be forgiven and the Lord will remember their sins no more. Such an individual can reinstate himself [with the help and counsel of priesthood leaders] to worthily partake of the emblems of our Lord”
